Justine Diener-O’Leary

Doctoral Intern in Psychology


I strive to create a safe, judgment-free space for my clients to explore their authentic selves, to develop self-compassionate strategies for change, and to gain insight into the contextual, internal, and external roots of their concerns, as well as pathways forward. I work collaboratively with my clients to identify their strengths and values and to help them feel empowered to make meaningful change in their lives.

Justine is a Doctoral Intern in Psychology at Vanderbilt University’s Counseling Center and is in her final year of doctoral training in Counseling Psychology at the University of Nebraska-Lincoln. Justine has worked with diverse client populations at university counseling and private practice settings. She currently provides individual and group therapy, as well as psychological assessment. Justine approaches treatment from a person-centered, feminist approach, valuing the unique perspectives, strengths, and experiences of each of her clients. She also integrates other approaches and techniques, including interpersonal, ACT, DBT, self-compassion, and mindfulness. Her clinical interests include trauma-focused concerns, identity development, women’s issues, relationship concerns, anxiety, and psychological assessment for ADHD/LD concerns. Justine also strongly values prevention and outreach and believes in the importance of understanding systemic oppression, power, and privilege and the role of social justice in mental health. When she is not in the office, she enjoys spending time with her family, hiking, kayaking, being in nature with her two dogs, reading, and traveling.
